How to Apply Beneficial Nematodes (Scanmask)

Created by Mark on July 31, 2016 at 4:31 pm

I live in Houston TX. Can Beneficial Nematodes be applied in the summer (90+ degF)? How often will I need to treat? (because these are living organisms, I’m expecting them to be self perpetuating, but want to be sure.) Thanks.

Beneficial nematodes are easily applied using no specialized equipment. Simply scatter over the infested area, then water. One pint will cover 200-400 square feet and will persist in soil for approximately 18 months. Killing action begins 24 hours after application and thousands of NEW nematodes can be produced — and released — from a single infected host.

Scanmask® is formulated to provide protection against UV light, heat and drying out. It has a shelf life of one year when refrigerated and can be applied most times of the year. However, to ensure full potency I recommend that you wait until temps drop down into the 80s before placing your order. I am concerned about how the package is handled en-route to you with such high temperatures. We’ve had some problems with shipments being left in the sun or a hot mailbox.
